Abstract: | The basic (2 C) nuclear DNA content has been determined for the first time in four primitive angiosperms by means of scanning densitometry of Feulgen-stained nuclei. The mean values obtained are the following:Liriodendron tulipifera L. (2n = 38): 1.58 pg;Magnolia soulangiana
Soul-bod. (2n = 76): 11.95 pg;Cinnamomum camphora
T. Nees (2n = 24): 1.18 pg;Illicium anisatum L. (2n = 28): 6.72 pg. These values do not represent extremes, but rank among low DNA amounts. All species display at least low degress of endopolyploidy. |
